The Opportunity:
At Roche's AI for Drug Discovery (AIDD) group (Prescient Design), we are revolutionizing drug discovery with cutting-edge machine learning (ML) techniques. We are seeking a Senior Machine Learning Scientist to join the Foundation Models team within Prescient Design (gRED). In this role, you will drive the development of our internal reasoning Large Language Models (LLMs) and enable it to succeed at drug discovery tasks, including biomolecular design. You will work at the intersection of engineering and research, designing and scaling large machine learning systems.
In this role, you will:
Technical Leadership & Strategy: Lead the design and evolution of scientific reasoning systems, setting technical direction for model architectures, training strategies, and evaluation methodologies.
Model Capability & Improvement: Define and execute approaches to systematically improve model performance on scientific tasks, including long-horizon reasoning and complex decision-making.
Domain Translation: Translate biological and chemical domain knowledge into machine learning objectives, training signals, and evaluation criteria, working closely with domain experts.
Scalable Systems & Engineering: Architect and improve large-scale distributed machine learning systems, ensuring robustness, efficiency, and reproducibility across training and evaluation workflows.
Research-to-Production Impact: Partner with researchers and cross-functional teams to move models from research prototypes to production-ready systems that support active discovery programs.
As a Senior ML Scientist:
You are the primary driver of technical implementation for scientific reasoning, translating high-level research goals into robust training code.
You own the end-to-end integrity of large-scale training runs, from data orchestration to the development of rigorous reasoning benchmarks.
You act as a technical mentor to junior staff and interns, fostering a culture of engineering excellence and rapid experimentation.
Who You Are:
PhD in Computer Science, Statistics, Mathematics, Physics, or a related quantitative field.
Experience: 0 – 2+ years of industry or post-doc experience with a focus on deep learning.
LLM Expertise: Extensive experience developing and training large-scale machine learning models, including approaches to improve domain understanding, reasoning capabilities, and model alignment.
Publication Record: A strong history of research excellence at top-tier venues (e.g., NeurIPS, ICLR, ICML).
Engineering: Strong software engineering skills and experience designing and operating large-scale or high-performance machine learning systems.
Preferred Qualifications:
Experience with molecular modalities (e.g., protein sequences, chemical graphs, and structured molecular data) is highly valued but not required.
A public portfolio of research or significant contributions to open-source ML libraries.
A passion for applying frontier AI to drug discovery.
Onsite presence on our campus is expected in compliance with Roche/Genentech policy.
Relocation benefits are not available for this job posting.
The expected salary range for this position based on the primary location of California is $168,100 - $312,300. Actual pay will be determined based on experience, qualifications, geographic location, and other job-related factors permitted by law. A discretionary annual bonus may be available based on individual and Company performance. This position also qualifies for the benefits detailed at the link provided below.
